CAR-COUPLING.

SPECIPICATION forming part of Letters Patent No. 388,856, dated September 4, 1888.

Application filed May 10, 15188. Serial No. 273,418.

To all whom, it may concern.-

Be it known that l, JonN GoETTEL, of Boston. in the county ofSuffolk and State of Massachusetts, have invented a new and useful Improvenent in Car-Conplings, of wlich the following is a specifcation, reference being had to the accompanying drawings, being a part hereof, in which- Figure l is a plan; Figs. 2 and 3, side eleto vations; Fig. 4, a section on line 4 of Fig. 2; Fig. 5, a plan of a pair ofcouplings; Figs. o and 7, views of one of the jaws detached; ad Figs. S and 9, views of the otherjaw detached. Fig. isa modification.

My improved copler consists of the main casting A, the lover-jaw B,held by pin b upon the main casting A, and the lover-jaw B',held by pin 1/ upon the nain casting A, the leverjaw B' being controlled by the spring If. When tle lover-jaws B are locked by the coupling-pin bi', Fig. l, which passes through a hole, If, in the main casting A, and also through a hole, If, near the inner end of the leverjaw B, (see Figs. 4, 5, 6, and 7,) the lcverjaw .B takes the draft, as clearly shown in Fig. 5, where the couplingpins b3 are not in place, in order to show the holes b4 in the nain castings A, which coincide witl the hole b5 in the iuer end of lover-jaw B. From Fig. 5 it will bc clear that removing the conplingpins b3 will uncouple, because each jaw B will then be free to turn upon its fulcrumb; but Willi the couplingpins b''i in place the jaws B cannot turn upon the fnlcruns I) and the looks on the jaws B will therefore remain hooked together. When the cars are going around curves, that corner a of part A to which jaw B is held by pinb approaches that corner a' of part A of the other coupling to wlieh jaw B' is held by pin b', this part a' of castig A, together with a portion of jaw B', serving as a guard to prevet uncoupling. If the jaw were in one piece witl the casting A, ny k coupling would not differ materially from others of the same class; and the main feature of my invention consists in the leverjaw B', fulcrumed to the main casting A, in combination with the hooked lever-jaw B and the spring b2, for by reason of this spring bAl my (No model.)

couplings can be coupled when the couplingpin b3 is in place or the hooked lover-jaws B be otherwise rigidly attached to the main casting A, for when the rounded outer ends of jaws B come in contact as the cars cone together each will be forced sidewise upon the inner surface ofjaws B/,whieh will yield, conr pressing the spring [Ilaud allowing each jaw B to pass the other until the two looks engage.

VVhile I prefer a spiral spring, I", as shown in Fig. 4, it will be clear that other forms of springs will answerfor example, that shown in Fig. 10.

My coupling can be coupled with either or both of jaws B locked, (by coupling-pin [i or any other locking device) or can be coupled 55 in the manner usual in couplings of this class Where it is necessary that the trainmen shall take pains that one or both of the hooked jaws B be unlocked from the main casting A and opened to allow the passage of the other hooked jaw B, whileI in other car-couplings of this class (each having a hooked lover-jaw) the couplings are often broken when by accident they are forced together with the hooked jaws B locked.

lt frequently happens that it is necessary to push a car by running another car against it When it is not desired to couple those two cars together, and in this case with my improved coupling, if either of the couplingpins l3 be So out of place, these cars will not be conpled, for one of the hooked lovers B will turn upon its fulcrun b Whenever a draft comes upon its hook if not locked.

As a matter of extra caution, a pin may be inserted in the holcs a2 which coincide with the hole ai* in the lever-jaw B', and thejaw B' be thereby locked to the main casting A.

\Vhat I claim as my invention is-` In a ear coupler, the eonbination, with the main casting A and hooked leverjaw B, of the leverjaw and its spring` N, substantially as set forth.
